Can be used with most co2 systems. This patented system has a extended diffusion path within a smaller area providing longer contact time to ensure efficient diffusion (absorption) of c02 in the aquarium

You just have to be careful to place it as close to perfectly straight as possible for the bubbles to more through the diffuser properly
